陈 亮 %A 梁昌洪 %A 党晓杰 %J 物理学报 %D 2007 %I %X Based on the electromagnetic theory,the Manly-Rowe relations for nonlinear left-handed metamaterials are studied.Energy conversion process and spatial distribution of forward-propagating wave of fundamental frequency and backward-propagating second harmonic wave under phase-matching condition are investigated.That a surface of nonlinear left-handed metamaterials operates as an effective mirror which reflects the energy in the form of second harmonics is demonstrated.Numerical results of field intensity distribution of a finite thickness metamaterial slab is given.Finally,the importance of phase-matching condition to the investigation of nonlinear left-handed metamaterials is illustrated from the viewpoint of phase-mismatching.This work provides a basis for studying nonlinear left-handed metamaterials. %K left-handed metamaterials %K nonlinear effect %K second harmonics %K phase-matching condition
